WINDOW-SCREEN.

Specification of Letters Patent.

Patented June 10, 1919.

Application led November 5, 1917, Serial No. 200,329. Renewed May 5,1919. Serial No. 295,025.

To all whom it may concern:

Be it known that I, JOSEPHA Z. CoLLET'rn, Jr., a citizen of vthe UnitedStates` of America, residing at Fitchburg, in the county of Worcesterand State of Massachusetts, have invented certain new and usefulImprovements in Window-Screens, of which the following is aspecification.

This invention relatesto certain new and useful improvements in windowscreens and relates particularly to window screens of the sliding type.

It is the especial object of the present invention to so construct ascreen of the above type as to present a most efficient device of itskind and which is durable and simple in plan of construction.

Another object is to provide a renewable metal bound screen sectionwhich'is capable of being quickly attached to and removed from thesliding frame which carries the same.

A further object is to provide novel means whereby the window sashes arelocked against being lowered and the screen locked against being raisedfrom the outside of the dwelling equipped with the same.

A still further object iS to provide guideways for the screen and meanscarried by the screen and engaging one of the guideways to lock thescreen in lowered position or to lock the Same in adjusted raised p0-sitions.

Vith the above general objects in view and others that will becomeapparent as the nature of the invention is better understood, the sameconsists in the novel form, combination and arrangement of partshereinafter more fully described, illustrated in the accompanyingdrawings and claimed.

In the accompanying drawings forming part of this specification and inwhich like reference characters indicate similar parts throughout theseveralviews;

Figure l is an inside sectional view o-f the lower portion of a windowwith the present invention in position therein and taken on line I-I ofFig. 2.

Fig. 2 is a vertical sectional view of Fig. 1 taken on line II-IIthereof.

Fig. 3 is an enlarged fragmentary perspective view of portions of one ofthe guideways.

Fig. 4 is an enlarged perspective view of Fig. 5 is an enlargedperspective view `of the lock carried by the upper end of the screen.

Fig. 6 is a fragmentary perspective view of one of the upper cornerportions of the screen with the removable transverse strip removed, and

Fig. 7 is a fragmentary perspective view of one end of the upperremovable strip.

Referring more in detail to the drawings, the invention embodies arectangular screen strip 1 whose edges are provided with a metal binding2. The screen strip 1 is carried by a Sliding frame composed of sidestrips 3 and 4, a lower end'strip 5 and a ivemovable upper end strip 6.The inner edges of the strips 3, 4, 5 and 6 are provided withlongitudinal grooves 7 8 and 9 and the upper ends of strips 3 and 4 areeach bifurcated to provide two spaced legs 10 and 11 between which isadapted to be secured one of the reduced ends 12 of the strip 6 by anysuitable means, such as the screws 13 shown by dotted lines in-Fig. 1which enter the apertures 14 and 15 of the bar 3 or 4 and the bar 6respectively. In assembling the device, upper bar. 6 is removed, themetal bound screen section 1 slid downwardly into position in thegrooves and the bar 6 secured in position, and it will be apparent thatthis construction provides an inexpensive, Simple and durable means forrenewing the screen section when damaged or worn from extended use.

In order to guide the screen in its vertical sliding movements, Iprovide channel bars 16 andr 17 which have their transverse portions 18Secured to the window frame 20 by means of screws 19.

The Screen is retained in position, as shown in Fig. 2, outwardly of thesashcs 21 and 22, and in order to prevent the sash 21 from being loweredfrom the outside, I provide a lock 23 which is detachably attached tothe upper portion of the screen by means of the screws 24 and keyholeslots 25. This lock is preferably formed of an elongated metal strip,one of whose ends are bent at right angles to provide a lip 26 whichengages the under face of the lower rail of the sash 21 as shown inFigs. l and 2 and the other end of the lock 23 is slitted to produce anarrow strip which is curved and bent outwardly to provide a handle 27.

In order to prevent the screen from being raised from the outside and tolock the same in adjusted raised positions, I cutaway a portion of thelower end of the guide 17 to provide a shoulder 28 under which engagesthe outwardly bent portion 29 of a lock 30 which is pivoted for lateralswinging movement to thelower portion of the screen by means of a screw31. The lock 30 is preferably formed with a handle 32 similar to thehandle 27 of lock 23 and in order to add to the eiiciency of the lockthe portion 29 thereof is extended upwardly as at 33 to embrace theguide. When it is desired to raise the screen, the lock 30 is swung outof engagement with the shoulder 28 as indicated by dotted lines in Fig.l and the handle 34 grasped to raise the screen. The screen may belocked in adjusted raised positions by swinging the lock 30 into eitherone of the notches 35 and 36 of the guide 17, as desired.'

While the form of the invention herein shown and described is what isbelieved to be the preferred embodiment thereof, it is iievertheless tobe understood that various forms, modifications and arrangements ofvCopies of this patent may be obtained for the parts may be made withoutdeparting from the spirit and scope of the invention as claimed.

What I claim as new is l. A window screen including arectangular'grooved fram'ehaving a removable end strip, and a metalbound screen section removably slidably positioned in the grooves ofsaid frame.

2. The combination with a sliding window screen of a notched guide-Waytherefor and a pivoted lock attached to the lower end of the screen andremovably engaging in the' notches .of the guide-way to lock the screenin lowered position Vor in adjusted raised positions.

3. A locking member adapted to be attached to the upper portion of asliding window screen to prevent the upper sash ofa window from beingloweredhi'rom the outside of a dwelling comprising a strip of metalhaving key-hole slots Vtherein and having one of its ends bent at rightangles to engage the under face of the lower rail of a window sash andhaving its other end slitted to produce a narrow strip which is curvedand bent outwardly to provide a handle.

In testimony whereof I aiiX my signature.
